It was recently reported that in the United States 35 million people board public transit systems each weekday. In 2011, Americans took over 10.2 billion trips on public transportation. Considering these numbers it becomes even more important to assess transportation safety and leave nothing to chance. Trains, planes, boats and automobiles are of course the most commonly thought of types of public transportation. We hear of planes and ships getting hit by lightning all the time and last year in China a bullet train was struck leading to one of the largest transportation disasters in the China’s history. Gondolas, however, although commonly used in mountainous regions and at ski resorts are not as commonly known, but more abundant than you know and used year around. They are also much more vulnerable due to their height and the geological make-up of where they are located. Electrical discharges from lightning can and do compromise cable-propelled transit systems, virtually making them useless, while also threatening passengers’ safety aboard the cable cars.

Just last week in Salzburg, Austria, a gondola system was shut down due to a lightning strike, leaving about 150 people stranded while visiting the Eisriesenwelt ice caves. Thankfully, when the lightning struck, the cable car was unoccupied. The tourists were led down the mountain by guides from the ice caves via a steep 500 meter path. Elderly and disabled sightseers were taken down in the gondola in emergency mode. One German tourist suffered a leg injury during her descent and was carried down via stretcher. The remaining tourists returned to the lodge safely, 2.5 hours later. Should the gondola system have been utilizing lightning protection and prevention systems, these tourists would not have been stranded atop the icy mountain.

In contrast, Telluride Transit Gondola Company sees the importance of protecting their 2.25 million passengers (annually) and eliminating the threat of lightning strikes to their 8 mile public transit and ski lift systems, between the town of Telluride and Mountain Village, Colorado. This Colorado area averages 7,300 Cloud to Ground (CG) lightning strikes per year. Prior to installing Lightning Eliminators & Consultants, Inc. (LEC) DAS™ solutions, the towers and stations were hit repeatedly by lightning strikes. After implementing DAS™ hemispheres on the towers, DAS™ Ridge Arrays on the stations, and Chem-Rods™ on all structures in 2001, lightning strikes have been averted from terminating the protected areas, even in the extreme conditions of wind, snow, ice, and vibrations.

LEC‘s lightning elimination system at Telluride minimizes downtime due to storms. Telluride’s local economy depends a great deal on its annual tourists, so getting people to their destinations faster gives them more time on the ground, which, in turn, benefits the local economy.
